Detailed description of the invention
Entry port of the present disclosure separately or and cannula assembly the roughly liquid-tight sealing provided between patient's body lumen and external environment is provided.Entry port of the present disclosure or black box are configured to the surgical unit receiving variable-diameter.The various operative procedure of imagination comprise peritoneoscope and arthroscopic surgical procedures.
Entry port of the present disclosure is it is contemplated that introduce various types of instrument, these instruments are suitable for being inserted by the trocar (trocar) and/or cannula assembly, maintaining roughly fluid sealing interface at surrounding equipment simultaneously, to help keeping the atmosphere globality of operative procedure, gas and/or fluid leaks can not occur.The example of apparatus includes but not limited to applicator (clip appliers), grabber, dispenser, traction apparatus, anastomat, laser microprobe, photographic equipment, endoscope and peritoneoscope, pipe etc.This instrument will be called " instrument " or " apparatus " jointly.
Describe the embodiment of disclosure device in detail referring now to accompanying drawing, in these figure each, like reference numerals refers to identical or counter element.As used herein, term " distally " refers to instrument or its parts part away from user, and term " nearside " refers to instrument or its parts part near user.Although what usually describe is use to enter assembly and carry out engagement notch herein, but it will be recognized that, this is only exemplary, be not intended to the use of limiter assembly by any way, it will be recognized that the disclosure is intended to use in any case on the contrary: enter assembly engagement notch, spontaneous aperture or any other suitable opening.
With reference to figure 1, disclose the entry port assembly 100 for being used in single incision surgery.Entry port assembly 100 is flexible or compressible, passes through single otch in patient body or opening inserts to allow it, makes after the insertion that it launches and seals in otch.In addition, the flexible nature of entry port assembly 100 allows surgical unit of being inserted by it to be handled relative to their respective axis, thus allows the movement of surgical unit relative high degree to locate them into the tissue be suitable for operated by it.
Especially, Fig. 1 illustrates the axonometric chart of the entry port assembly 100 proposed according to embodiment of the present disclosure, and it has multiple opening 18 and is beneficial to synchronously introduce multiple surgical unit 30.
Entry port assembly 100 comprises the entry port 10 defining tubular element 12.Tubular element 12 comprises proximal end 14 and distal end 16.The proximal end 14 of tubular element is securely fixed in tissue 20.Entry port 10 is stabilized in tissue 20 via stable anchorage part 40.Stable anchorage part 40 can be firmly-fixed to stationary objects.Entry port 10 can comprise central opening 50.Opening 50 can extend into the length of the tubular element 12 of port one 0.It is envisioned that additional surgical instrument can be inserted by opening 50.It is also be envisioned that surgical hands can be inserted by opening 50.Also, in the scope of example embodiment, during several operative procedure, opening 50 is closed.Also within the scope of the disclosure, another operation entry port is positioned in opening 50.Suitable entry port is described in the U.S. Patent application of the serial number 12/244,024 being filed on October 2nd, 2008 completely, and its whole content is by reference to being incorporated to herein thus.
Distal end 16 comprises periphery 25, and periphery 25 is configured to and is sized to the multiple opening 18 of restriction be beneficial to synchronously introduce multiple instrument 30.Opening 18 is configured to the outer wall of the tubular element 12 extending through entry port 10.Each in multiple instrument 30 can be inserted by the proximal end of entry port 10 14 (together or independent), and the length that can extend through the outer wall of entry port 10 or the whole of periphery is to leave opening 18.Multiple passages 27 in entry port 10 are the chamber or the path that are suitable for receiving elongated surgical instrument 30.Thus, surgeon can handle multiple surgical unit 30 during single operative procedure simultaneously, and does not need constantly from operation field insertion/removal instrument.In addition, it is noted that each in multiple surgical unit 30 can be independent exercisable.
In addition, in the structure of Fig. 1, multiple surgical unit 30 can be inserted by proximal end 14, and leaves multiple opening 18 at distal end 16 place of entry port 10.In this example embodiment, opening 18 is equidistantly spaced apart each other.But the location of multiple opening 18 can adopt various structure, discuss below with reference to Fig. 2-5.
Multiple instrument 30 can be controlled by wired or wireless method.In addition, at least one in multiple instrument 30 can be mechanical arm.Certainly, all multiple instruments 30 can be mechanical arms.
Term " tubulose " for describing entry port 10 used herein is intended to comprise various cross sectional shape, comprises circle, ellipse, rectangle etc.In addition, entry port 10 can not have continuous print solid wall, but longitudinal or circumferential slit or hole can be had, or the cage of enough rigidity or web frame can be had to maintain the shape of multiple opening 18 and open (patency) when being positioned in tissue 20.
Entry port 10 can be made up of any various biocompatible material.But because these parts can run through into body cavity and contact biological tissue, they are normally aseptic.Therefore, entry port 10 is preferably made up of the material that can sterilize between use, or by being formed by the material disposed after every use.The sterilizable material being suitable for entry port 10 comprises rustless steel, anodised aluminium and other biological biocompatible metal.Have desired properties characteristic can also low cost dispose material comprise plastics, such as Merlon, acetonitrile butylstyrene (ABS) or polrvinyl chloride (PVC).
In example embodiment of the present disclosure, the position maintaining entry port 10 is realized by rigidity or semi-rigid anchorage element 40, and rigidity or semi-rigid anchorage element 40 can be fixed to the stationary objects of operating board or other supporting constructions or any other type.Some dissimilar fixture constructions can be arranged for entry port 10 adjustable ground is attached to anchorage element 40.In one embodiment, entry port 10 can rely on collar (collar) (not shown) to be attached to anchorage element 40, this clip at entry port 10 near its proximal end, near preferred upper limb.Collar can be attached to anchorage element 40 pivotally by ball-and-socket joint (not shown), and ball-and-socket joint can be locked in ad-hoc location by such as one or more setting bolt (not shown).In like fashion, entry port 10 can be positioned in body cavity and to be manipulated to expected angle orientation, makes operative site visible by multiple passage 18.
In addition, entry port 10 of the present disclosure can receive the object changing diameter during Minimally Invasive Surgery program, such as, comprises the instrument of about 4.5 millimeters (mm) to about 15 millimeters (mm).And, various types of instrument be introduced and be handled to entry port 10 can, these instruments are suitable for being inserted by the trocar and/or cannula assembly, maintain fluid sealing interface simultaneously produce pneumoperitoneum, to keep the atmospheric integrity of operative procedure to prevent gas and/or fluid leaks at surrounding equipment.
